Adobe Photoshop CS3 updater quits

I recently bought the new iMac and I installed my Adobe CS3 onto it. Everything seems to be working fine but the Photoshop updater would quit upon opening. So I can't get the needed updates to view my RAW files. Also, when I tried to go and download the updates myself, Photoshop shows me this; "Could not complete your request because Photoshop does not recognize this type of file." Is there anything I can do to fix this problem?
